for Use in LD‑Driven White‑Light Lamp

Graphical Abstract


 
Highlights

Highly efficient and highly conductive phosphor-in-glass (PIG) material with additives for use as a white conversion component in laser-diode-driven white-light systems is introduced.

light extraction efficiency was investigated by modulating the ratio of the additive in a simulation using a light extraction model.

On the basis of simulation results for the proposed PIG, both transmission-type and reflection-type sapphire phosphor-in-glass samples were fabricated and evaluated

It has been confirmed that the sapphire powder significantly enhanced the light extraction efficiency and heat dissipation of the system.
